yes, correct, and we already fixed several issues
the changes caused, both in handling as well as
functionality

of course it is testing, but it is already in
mainstream, and for my part, I wasn't able to
provide feedback from testing yet ...

we do the same testing you folks do IIRC
(i.e. some secret test procedure which takes
roughly a week or so, after which we can tell
that everything works as expected :)

nice, but what relevance has that for 2.6.19?

cool, how much feedback regarding IPC did you get
since then?

it's good that some bugs have been found, but
of what relevance is that for testing mainline
patches?
- typical linux users will only excercise a
small fraction of the new code, if at all
- virtualization solutions like OpenVZ and
Linux-VServer add their custom modifications
and/or adjustments, and serve a much smaller
userbase
- I haven't seen any test suites or similar
for the spaces
so it all boils down to waiting for somebody to
stumble over an issue, which then will get fixed
just that the number of folks testing that is
quite small compared to 'other' mainline pathes
anyway, originally I was just answering to an
email pushing for 'fast' inclusion, which I do
not consider a good idea (as I already stated)
